The Leasing Desk Guide (Desk Guide) chapters contain authorities, policies, technical and procedural guides, and administrative limitations governing the acquisition by lease of real property. It replaces previous Public Buildings Service (PBS) leasing guides and incorporates other existing policies and procedures. Additional Realty Services Letters (RSL) are available in the Other Policy Information section. Realty professionals must follow the policies of the effective RSL until they are canceled by additional Desk Guide issuances and/or Lease Acquisition Circulars (LAC). The process overviews in this Desk Guide do not completely cover all of the possible considerations and alternative courses of action that realty professionals must know to successfully complete all possible lease actions. However, they should be able to use the material in this Desk Guide to help them tie together the typical considerations, process steps, and review requirements that they could normally expect to encounter.
